Description

[Detailed Description of the Invention] The present invention relates to an umbrella-shaped tent that is easy to open and close.

The purpose of this invention is to provide an umbrella-shaped tent to be installed in amusement parks, squares, and other appropriate locations, by providing a driving force transmission mechanism on the top of the erected base pipe, and operating this manually or by power drive. To provide an umbrella-shaped tent that can be opened and closed smoothly and easily.

That is, in the present invention, tension rods 3 for the tent sheet S are pivotally attached to the top of a vertical movement tube 2 that is loosely inserted into a base tube 1 that is erected, so that they can be opened and closed radially, and tension rods 4 for opening and closing the tent sheet S are pivoted so as to be able to open and close them radially.
One end is pivotally supported on the tensioning rod 3 and the other end is pivotally supported on the sliding body 5 fitted into the base pipe 1, and the vertical motion pipe 2 and the sliding body 5 are
A transmission mechanism 7 provided at the upper part of the base pipe by a connecting cable 6
A rack 10, which is connected to the pulley 8 of the
This is an umbrella-shaped tent characterized by having a drive member 11 connected to a pinion 9.

In the illustrated embodiment, the base rod 1 is erected with its lower end opening fitted into a base column 13 which is removably fitted into the upper part of the embedded body 12 having an anchor member 12a and a bottom plate 12b. Reference numeral 13a indicates a stop pin protruding from the base column 13, and 12c indicates a locking shelf having a base insertion hole 12d that receives the stop pin 13a on its upper surface and has a passage hole therethrough. The sliding body 5 has pivot pieces 5a radially equal in number to the number of tension rods 4, and the lower ends of the tension rods 4 are pivotally supported by the pivot members 4a, while one end 6a of the connecting cable 6 is is fixed by a fixture 6b. The other end 6c of the connecting cable is fixed to a mounting plate 6d attached to the lower end of the vertical movement pipe 2 by wrapping a pulley 8 around it. The pulley 8 of the transmission mechanism 7 coaxially has a pinion 9 that meshes with the rack 10. A driving worm gear 14 meshes with the pinion 9, and the gear 14 has a locking member 1 on which the hook 15a of the operating handle 15 is hooked.
4a is installed. The driving means is not limited to manual driving, but electric or other powered driving means can be installed as appropriate. Reference numeral 16 denotes a pivot plate of the tensioning rod 3, which is attached to the upper end of the vertical movement pipe 2 and has the same number of pivot pieces 16a as the tensioning rods 3 radially provided therein, and 17a is a shaft extending to the center hole 17b of the tent sheet S. The shaft hole 18 of the retinaculum 17c is a cover that clamps and holds the tent sheet S between the pivot plate 16 and the set screw 20 in the screw hole 19a of the receiver plate 19.
are screwed together through the center hole 18a and the shaft hole 17a. Further, 21 is a tensioning rod that is elastically loaded at the tip of the tensioning rod 3 via a spring 22, 23 is a tensioning bag portion of the tent sheet S into which the tensioning rod 22 is placed, and 24 is a tensioning rod that connects one end of the tensioning rod 4 to the tensioning rod. The pivot member 3 is connected to the pivot member 4b at the other end of the tension rod. The planar shape of the tent may be arbitrary, such as circular or polygonal (Figure 4).

In the above configuration, when the driving member, that is, the worm gear 14 is rotated in a predetermined direction by turning the operating handle 15, the vertical movement tube 2 can be raised because the pinion 9 is engaged with the rack 10. As the vertical movement pipe 2 rises and the fixed length of the connecting cable 6 also moves upward within the base pipe 1, the sliding body 5 descends due to its own weight and the loads of the tensioning rod 3 and tent sheet S, raising the umbrella-shaped tent. When the handle 15 is turned in the opposite direction, the connecting cable 6 pulls up the sliding body 5 as the vertical movement pipe 2 descends, and the tension rod 4 pushes up the tension rod 3 relatively, so that the tent closes. It becomes tense.

Therefore, according to the present invention, the driving force transmission mechanism 7 is provided at the upper part of the erected base pipe 1, and by operating the transmission mechanism 7, the vertical movement pipe 2 can be raised and lowered to close or open the umbrella-shaped tent. Since a pinion 9 and a rack are used for 7, tensioning is easy and there is no risk of the tensioner being closed unexpectedly from the open state.
